MIDI sequencer I/O and enumeration

Structs

• Addr
  snd_seq_addr_t wrapper
• ClientInfo
  snd_seq_client_info_t wrapper
• ClientIter
  Iterates over clients connected to the seq API (both kernel and userspace clients).
• Connect
  snd_seq_connect_t wrapper
• EvCtrl
• EvNote
• EvQueueControl
  snd_seq_ev_queue_control_t wrapper
• EvResult
  snd_seq_result_t wrapper
• Event
  snd_seq_event_t wrapper
• Input
  Struct for receiving input events from a sequencer. The methods offered by this object may modify the internal input buffer of the sequencer, which must not happen while an Event is alive that has been obtained from a call to event_input (which takes Input by mutable reference for this reason). This is because the event might directly reference the sequencer’s input buffer for variable-length messages (e.g. Sysex).
• MidiEvent
  snd_midi_event_t Wrapper
• PortCap
  SND_SEQ_PORT_CAP_xxx constants
• PortInfo
  snd_seq_port_info_t wrapper
• PortIter
  Iterates over clients connected to the seq API (both kernel and userspace clients).
• PortSubscribe
  snd_seq_port_subscribe_t wrapper
• PortSubscribeIter
  Iterates over port subscriptions for a given client:port/type.
• PortType
  SND_SEQ_PORT_TYPE_xxx constants
• QueueStatus
  snd_seq_queue_status_t wrapper
• QueueTempo
  snd_seq_queue_tempo_t wrapper
• Remove
  SND_SEQ_REMOVE_xxx constants
• RemoveEvents
  snd_seq_remove_events_t wrapper
• Seq
  snd_seq_t wrapper

Enums

• EventType
  SND_SEQ_EVENT_xxx constants
• QuerySubsType
  snd_seq_query_subs_type_t wrapper

Traits

• EventData
  Internal trait implemented for different event type structs (EvNote, EvCtrl, etc).
